Solitons in Bose–Einstein condensates
The Gross–Pitaevskii equation (GPE) describing the evolution of the Bose–Einstein condensate (BEC) order parameter for weakly interacting bosons supports dark solitons for repulsive interactions and bright solitons for attractive interactions. After a brief introduction to BEC and a general review of GPE solitons, we present our results on solitons that arise in the BEC of hard-core bosons, whi...
متن کاملBright Solitons in Bose-Einstein Condensates
It is a well-known fact that the interplay of nonlinearity and dispersion leads to the appearance of localized wavepackets moving without distortion. When the interaction between atoms is attractive (resp. repulsive), bright (resp. dark) solitons can be generated in BEC. Note that the term soliton is usually reserved to the localized solution of an integrable system [1]. Elastic scattering is a...
متن کاملAnisotropic solitons in dipolar bose-einstein condensates.
Starting with a Gaussian variational ansatz, we predict anisotropic bright solitons in quasi-2D Bose-Einstein condensates consisting of atoms with dipole moments polarized perpendicular to the confinement direction. Unlike isotropic solitons predicted for the moments aligned with the confinement axis [Phys. Rev. Lett. 95, 200404 (2005)10.1103/PhysRevLett.95.200404], no sign reversal of the dipo...

متن کاملCoherent Molecular Solitons in Bose-Einstein Condensates
We analyze the coherent formation of molecular Bose-Einstein condensate (BEC) from an atomic BEC, using a parametric field theory approach. We point out the transition between a quantum soliton regime, where atoms couple in a local way to a classical soliton domain, where a stable coupledcondensate soliton can form in three dimensions. This gives the possibility of an intense, stable atomlaser ...
